Ref: #162
Summary
This PR deprecates native promises in crew in favor of the latest in Shiny and development mirai. Thanks to event-driven promises, crew can rely on individual mirai objects to invalidate reactive expressions, even in the presence of thousands of tasks. The new Shiny integration vignette shows how this works. It's just as user-friendly as before, and it makes controller$promise() completely obsolete.
I will wait to merge this until the next versions of mirai and nanonext are released.
